What is Covid-19?

Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Coronavirus disease(COVID-19) is the infectious disease caused by the most recently discovered coronavirus. The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.

Note: The main aim of this kernel is not to dig deeper into where and how fast corona virus is spreading. It isn't to extensively study the havoc wreaked by the coronavirus in different countries either. Rather, it is to understand the extent of the spread and notice how vaccinations are helping us ease it down. It is to educate all and sundry about the importance of vaccinations with regard to Covid-19.

Hence, I'll focus on the subject of vaccination.

I shall begin this EDA by peeking through the two datasets in the covid-19-global-dataset. This is to be aware of the current active cases and the rate of transfer of the coronavirus right from the very start.

I've used chloropleth maps to portray the spread of coronavirus chronologically and globally. I've used a steady yet stagnant chloropleth to display the current active cases all over the world. Pretty self-descriptive, eh?

Now that we've been briefed on the situation, let's learn how we can tackle this.

Vaccination Progress

The dataset contains the following information:

1. How many people are vaccinated in each country?

Since the number of total vaccinations and the people vaccinated as of today match, we can confirm that China, USA and India are the leading countries in having their citizens vaccinated.

2. Which countries have the most number of fully vaccinated people?

3. What's the trend noticed when comparing date with daily vaccinations?

We, very clearly, see an increase in the number of daily vaccinations. And this increase is definitely commendable!

4. a) Total vaccinations in India

4. b) Daily vaccinations in India

A conclusion with regard to this plot is that there is definitely a noticeable increase in the number of vaccines administered in India. Sadly, there is no age group mentioned in this dataset else that would have been an option to explore as well. Health officials said that an increase in awareness and fear of the second wave has made people go for vaccination. They said that the number of people getting vaccinated would increase two-fold in the coming days as the number of cases was on the rise.

5. Which is the most popularly used vaccine?

6. Which country prefers what vaccine?

With the help of an interactive treemap and a chloropleth, I've made an attempt to visualize the preferred vaccines in the respective countries (the popular aspect included).

Why vaccines can bring about a change?

To assure the efficacy of the vaccines, let's take into account a before-after scenario.

Consider people fully vaccinated (per hundred) in the United State of America.

From the choronologically arranged chloropleth, let's observe the number of cases on 15th Jan, 2021 and 1st May, 2021 and compare: We notice that the cases on 15th Jan, 2021 total to 8742806. However, the cases take a nose dive to 6589842 as of 1st May, 2021 (aka after the administration of vaccines) Hence, there's definitely a reduction in the number of active cases.

Let's consider another country to cement this observation well. Let's take UAE this time and follow the same steps.

On 15th January, 2021, the active cases are about 26655. As of 15th April, 2021, the number of active cases drop to 14866. Once again, confirming the observation that yes, vaccines are efficient and they play a huge role in mitigating this spread of the virus.

A gist

Special thanks to Sharlto for this amazing resume chart.

There's no way to tell how long the pandemic will continue. There are many factors, including the public’s efforts to slow the spread, researchers’ work to learn more about the virus, their search for a treatment, and the success of the vaccines. Remember, the best covid vaccine is the one available to you. So, wait for your chance and go take a shot! Help others get others and convince them in all the ways you possibly can. Wear a mask (even if you're fully vaccinated), use sanitizers and I'm guessing by now, you know the drill! Hoping to see the end point in sight, let's bring this virus down, together!

Thank you for reading this far. All your opinions are welcome!
